at the picture，'wait' is a custom step
I run teststand seq, will pop up labview crash as attachment
anyone could help me? thank you very much!
As interesting as this picture is it will be difficult to properly diagnose the issue without further information.
But it appears as if your custom step is calling some LabVIEW wrappers around the TestStand ActiveX API and this is what is causing the issue.
Perhaps you could create a small, reproducible example and post this to help us troubleshoot further.
